68 AIM revision Date
« on: December 10, 2009, 02:09:36 AM »
To anyone with 68 AIM,
Need to know the 1st revision date on K30 A2 #1, looks like 5 ? 67. This will answer some questions about my 5E build.
Thanks,
Bob

Definitely hard to read.  Sometime in the 20s, looking at the numbers below it, the first number is definitely a "2". I was going to deduce it is the 28th, but the 28th was a Sunday in 1967...  Maybe a 24, which was a Wednesday.

Phillip,
How does 3 23 67 look to you?

It's 5-20-something or 6-20-something - the sheet was originally released on 5-24-67.

John,
Were the revisions  in AIM done before, or after the line production change?
The reason I am asking about the revision is that I have an 5E 67 build with the correct firewall and fender-well piercing that is shown in the 67 AIM. The regulator bracket 3927351 that is shown in the 68 AIM looks like the Brk. I have, not the one that is shown in the 67 AIM 3901771. The revision indicates that there was a change that took place around my build date. Do you think that it could have been possible for an 5E build to have the newer bkt.?
I bought the car from a car rental agency in 1970 and have had it ever since.

Watchout when comparing Service part numbers to the Engineering part numbers used in the AIMs.  They are not the same in most cases.

Looks like the 29th to me.

There's no solid relationship between the AIM date and the implementation of a change on the line.
John has posted more info on it in the past, but the events can be months apart.

So, where revisions always done before the implementation of a line change, or could there possibly have been a line change and then the revision?
I want to thank you and all the members who try to answer my questions.

The date in the revision block only indicates when Engineering Graphics released the revised sheet; the actual implementation date on the line was handled through the NPC (Notice of Production Change) system. Those were internal documents, and seldom saw the light of day. Generally speaking, implementation occurred after the revised sheet was released, but some changes occurred prior to the revisiion date; you'd need the signed-off NPC (which had the VIN of the first car with the change implemented) to know for sure.

JohnZ,
Thanks for the explanation.
I have read your excellent paper on the Norwood assembly line procedures, several times, and it contains a wealth of information.
I wish there was a paper on the procedures, from the conception of a revision, to Engineering Graphics, to the implementation of the revision on the line.
Your latest information has put quite a few of the pieces together for me.
Thanks again.

He's already written that (for another publication) too. Hopefully it will be on the site in the future.
